"It didn't look good obviously, but we just have to wait and see," Doc Rivers said (via the Los Angeles Times). "Lonzo was just trying to make a play. Lonzo knocked somebody into Blake. And there was a trigger effect. What can you say?"

No foul was called on the collision during a scrum for a loose ball with 4:43 to play.

"You could see right when it happened," Doc Rivers said. "Lonzo was just trying to make a play, but he went in. Usually when you go in like that, that hard … they call it."

Griffin remained in the game for one possession, missing a shot, then checked out and headed to the locker room.

After the game, he left without speaking to reporters but wasn't on crutches, according to multiple reports.

Clippers' Blake Griffin (left knee) exited arena walking under his own power, no crutches or brace. Didn't take questions from media.

"He's not in high spirits. He's down," Doc Rivers said. "Right now he's where we are at, hoping it was just a bang and that it hurt and that he'll be all right."

Griffin has been dogged by injuries throughout his eight-year NBA career, having played in 67, 35 and 61 games the past three seasons. Yet the Clippers signed him to a new five-year, $173 million contract during this offseason.
